Claims.

This invention relates to tabulating machines and more particularly toimprovements in the printing mechanisms therefor.

The main object of the invention is to provide 5 an improved printingmechanism for printing alphabetical characters as well as digits inwhich the type characters are moved into printing position in a positivemanner. In carrying out the present invention the preferred meanscomprises a type carrying member provided with a plurality of groups oftype, one group, for example, being numeral type; a second,substantially a third of the letters of the alphabet; a third, thesecond third of the letters of the alphabet; and last, if so desired,the remaining letters of the alphabet. The several groups of type areoverlapped so that a numeral type is followed by a type of each of theother three groups and the numeral type are arranged to be normallypresented to the printing line as perforations in Hollerith record cardsregister with the usual record analyzing brushes. Each group ofalphabetic type is represented on the record card with what is known asa zoning perforation. These perforations apply only to the alphabeticcharacters, the numerical characters being indicated by singleperforations in the usual manner and the alphabetic characters beingindicated by a numerical perforation accompanied by a zoningperforation, thus forming a two-hole combinational reading. As therecord cards pass the analyzing brushes the numerical perforations arefirst sensed and cause the type bar to be positively advanced from aposition of rest to present the numerical type corresponding to thelocation of the perforation to printing position.

Following this, the zoning holes are analyzed by the same set ofanalyzing brushes and cause the further positive advance of the type barto select one of the type adjacent to the numeral type in accordancewith the location of the zon ing perforation on the record card.

A further object of the invention is to provide printing mechanismresponsive to perforations in a record card whereby repeated printingoperations may be effected from the same record card. In the well knownform of I-lollerith tabulating machine, two card analyzing stations areusually provided and known as the upper and lower brush stations. Withthe present arrangement of printing mechanism, analysis of alphabeticaldesignations may be made as the record card passes the upper brushes andprinting effected accordingly. As the card proceeds past the lowerbrushes, analysis may be made of alphabetic des- 1934, Serial No. rsatcc(or. nor-es) ignations in another portion of the card and caused tocontrol the same section of the printing mechanism. This arrangement hasparticular utility in printing names and addresses where the name is onone portion of the card and the address on another. Heretofore inmachines of this type it has been necessary to provide two record cards,one bearing the name and the other the address and throughout tabulatingoperations it has been necessary to keep these two related cardstogether. With the present arrangement, the obvious inconveniences ofusing two cards are entirely eliminated. In the operation of themachine, so-called address cards which contain a name and address areprovided with a distinguishing perforation in a selected index pointposition and the presence of this perforation is detected before thecard arrives at the analyzing stations and its presence causes themachine to pass the address card by the upper and lower brushescompletely before the next following record card is advanced.

Other record cards which are not classified as address cards move pastthe brushes in the normal manner; that is, as one card is passing thelower brushes, the next following card is passing the upper brushes.

Various other objects and advantages of the invention will be obviousfrom the following particular description of one form of mechanismembodying the invention or from an inspection of the accompanyingdrawings; and the invention also constitutes certain new and novelfeatures of construction and combination of parts hereinafter set forthand claimed.

Fig. 11 is a circuit diagram of the electric wiring of the printingcircuits of the machine.

Fig. 12 is a sample of a record showing the manner in which successivelines of alphabetic data are printed from the single record card.

Referring to Fig. 8, the record card R has the usual perforations forindicating numerical values as shown at the right end of the card. Thealphabetical characters from A to I are combinations of one of thenumerical characters from 9 to 1 plus a perforation in the R index pointposition. Characters J to R comprise a perforation in one of thenumerical positions 9 to 1 plus a perforation in the X index pointposition. The remaining letters of the alphabet, namely, S to Z,

comprise a combination including one of the perforations 9 to 2 plus aperforation in the zero index point position. The record cards R areplaced in the usual feed magazine (Fig. 9) from which they are fed oneby one by the picker ll into engagement with the usual feed rollers l2which convey the cards downwardly past the usual upper analyzing brushesU13 and exactly one machine cycle later past the lower analyzing brushesLB, after which the cards continue downwardly into the usual stackermechanism (not shown). The card feeding mechanism shown in Fig. 9 is orthe usual structure found in this type of machine. In the presentinstance, however, provision is made for suppressing operation of thepicker H and the uppermost pair of feed rollers for a cycle ofoperations so that the preceding card may first be completely passedthrough the machine. The manner in which this is effected will now bedescribed.

Shaft i3 may be driven continuously from a suitable source of powerduring the operation of the machine and is adapted to make onerevolution for each cycle of operations. Through gear-- ing, generallydesignated M, the three lower pairs of feed rollers 32 are rotated toadvance the card after it has passed the upper brushes UB. A gear E5 onshaft l3 drives a gear 15 to which is secured a clutch driving elementll rotatable on the shaft I8. Secured to the shaft 18 is an arm l9 whichhas secured thereto a gear 28 which meshes with a gear 2 l The gear 2|through eccentrically attached link 22 operates the picker H once eachrevolution of gear 2| and also serves to drive the uppermost feedrollers l2. Carried by arm i9 is a spring-pressed dog 23 which isnormally in engagement with driving element II so that the parts rotatein unison. A member 24 is normally adapted to be latched in the dottedline position by armature 25 and magnet 25. Energization of magnet 26will release the member 24 so that it will assume its full line positionand cause dog 23 to rock out of engagement with element l1 therebyinterrupting the operation of picker H and uppermost feed rollers l2.Toward the end of the cycle the pin 2'! carried by 8981' I5 will engagea laterally extending arm of member 24 and rock the same to its dottedline or latched position so that operation of picker l I will resumeafter an interruption of a single cycle. .Magnet 26 is energized undercontrol of a record analyzing brush 28 located slightly in advance ofthe brushes U3 and is adapted to sense a special designation indicatingthe presence of a so-called "address card.

Sensing of such perforation will cause energize.- tlon of magnet 26 in amanner to be pointed out in connection with the description of thecircuit diagram whereby the interruption of the operation of the upperpair of feed rolls l2 will permit the address card to completelytraverse both the upper and lower brushes before the next card is fed.Shaft 58 (Fig. 10) carries a com 233 which cooperates with followerroller 30 on arm 3!. Arm 3i carries a ball 32 of insulating materialwhich serves to hold contacts 33, 34 in the position shown in Fig. 10whenever shaft i8 is disconnected from driving engagement with the shaft13. When the parts are connected, the ball 32 is lowered throughout themajor portion of the cycle so that contacts 34 are closed and contacts33 open. The manner in which the contacts function and the circuitswhich they control will be further explained in connection with thecircuit diagram.

Printing mechanism The printing type bar is designated 35 in Fig. 1 andcarries at its upper end the type head 36 provided with type elements 31horizontally slidable in the head 36. The bars 35 are suitably guidedfor vertical reciprocation in the frame of the machine. Each type barcarries a pawl 38 pivoted thereto which is connected to a hook 39 whichis normally held in the position shown in Fig. 1 by a latch 45 which,when the type bar is in its lowered or restored position, tends to holdhook 39 upwardly against the tension of its spring at and bell crank 38is accordingly held in the position shown.

Integral with car 35 is a notched member 42 whose upper end terminatesin a finger 63 which also cooperates with latch Ml and restrains thetype bar 35 against upward movement. Extending across type bars 35 is aso-called carriage 44 which is given an invariable verticalreciprocation cach cycle of the machine from the position shown in Fig.1 to that of Fig. 3 and back again. Carriage 44 is provided with asuccession of ledges 45 numbered 9 to 1 and these ledges successivelypass the toe of pawl 38 as the carriage moves upwardly. At differentialtimes during the upward movement of the carriage pawl 38 may bepermitted to rock in a clockwise direction into engagement with one ofthe ledges 45. When this occurs the .pawl 38 and associated bar 35 willbe efiectively coupled to the carriage and will move upwardly therewithto present the digit corresponding to the engaging ledge in printingposition. 011 the return movement of carriage 44 the member it willengage a pin 41 in the lower end of bar 35 to cause the positiverestoration of the bar and a cam bar 48 extendlng across the top thecarriage will engage the toe of pawl 38 rocking it counterclockwise sothat hook 39 will be reengaged with latch 40. The initial tripping ofpawl 38 is effected under control of printing magnet 49 which uponenergization will attract its armature ill and draw spring-pressed linktoward the right. The left end of the link is connected to the free endof latch 40 and will accordingly disengage the same from hook 38 so thatspring 4| may draw the latter downwardly and rock pawl 38 intoengagement with a ledge of carriage. The manner in which carriage 44 isreclprocated will now be described.

The carriage is provided with pairs of rollers 52 (Fig. 1) which rideupon a vertical track 53. The lower end ot the carriage is connected bya.

link 54 (see also Fig. 2) to an arm 55 which in turn is connected by alink 56 to an arm 5! secured upon shaft 58. In Fig. 7, shaft 58 is shownas having secured thereto a double armed cam follower member 59 whichcooperates with complementary cams 60 secured upon shaft 6!. Shaft Si isadapted to make a single revolution for each cycle of the machine andmay be suitably geared to shaft 03 of Fig. 9 for rotation in synchronismtherewith so that each shaft will make one revolution per cycle of themachine.

Referring again to Fig. 1, each type bar is pro- .vided with a pin 52which, when the type bar moves upwardly, will permit counterclockwiserocking of a member 63 pivoted to the lower end of a latch tit so thatthe left end of member 63 will engage a ball 65. After the carriage "Mhas reached its uppermost position, bail be is rocked clockwise and inthose positions in which the type bar has advanced member t3 will bedrawn toward the left causing clockwise rocking of the attached latchesM. The latches be normally hold spring-pressed printing hammers 68 inthe position shown and since hammer restoring bail bit is out ofengagement with the hammers at this time, unlatching by M will permitprinting to take place and the type elements on the printing line willbe urged against platen ill. The operating mechanism for bails 65 and 6bis shown in Fig. 2 where shaft Sill supporting bail St has securedthereto the bell crank iii connected by a link ii to an arm i2 integralwith a double armed cam follower member i3 whose rollers cooperate witha pair of complementary cams M mounted on shaft ti. I

Bell crank lid is connected by a link it and am it to shaft ll uponwhich the bail $5 is carried and the timing is such that bail BS isretracted before bail 65 operates to trip the hammers. The hammertripping mechanism per se forms no part of the present invention andonly so much thereof has been described as is necessary for anunderstanding of the operation.

It will be understood, of course, that the upward movement of carriage44 is in synchronism with the movement of the record cards past theanalyzing brushes in such manner that the ledges 9, 8, 7, etc.,successively pass the toe of pawl 3b as the corresponding index pointpositions of the record cards pass the analyzing brushes. Near the endof the upward stroke of carriage Mi a secondary carriage i8 is movedupwardly. Carriage it has pivoted thereon spring-pressed pawls itnormally held in the position shown in Fig. l by latches 8tspring-biased in a clockwise direction. The latches til are providedwith upwardly extending fingers ti which, as carriage it moves upwardly,come within the range of members tit pivoted at 83. The upper extremityof members ii? are connected to links bi so that energization of anymagnet it will rock its member 82 clockwise causing counterclockwiserocking of the member dd so that pawl it will be urged into engagementwith notched member if and, depending upon the time of energization ofmember 69, bar 35 will be advanced by carriage it an additional 1, 2, or3 steps to select the first, second or third alphabetic characteradjacent to the previously selected numerical character.

The position of the parts for the selecting of the character P is shownin Fig. 3 wherein carriage M is shown in its extreme upward position andpawl 38 in its dotted line position indicates the extent to which it isadvanced by car'- riage it after having been tripped into engagecarriageM at the upper end of its stroke.

ment with a ledge 45 under control of the perforation in the 7" indexpoint position of the card, this position being one of the combinationassociated with the character P. As the carriage l8 subsequently movesupward the reenergization of magnet 49 trips pawl 19 into engagementwith the member 42 as shown and bar 35, together with pawl 38, advancesupwardly two additional steps, bringing pawl 36 to the full lineposition and moving the type head 36 two additional steps beyond the 7"position. This, it will be observed in connection with Fig. 5. is theposition in which the character P occurs.

Since magnet 49 may be energized twice during the cycle in response toeach of the pair of combinational perforations, it is desirable toeffect restoration of the armature 50 during the interval betweenenergizations of the magnet. This is effected by means of a bail 84carried by shaft 85. In Fig. 2, shaft 85 carries an arm 86 whose freeend supports a link 87? connected to an arm M on a stud as. Link ti andarm 38 form a. toggle connection whose common center is. connected by alink Qii to a bell crank bi pivoted on shaft 92. The other arm of bellcrank ti carries a roller 93 which traverses the periphery of a cam timounted on shaft 6 i. As the cam rotates clockwise the arm carryingroller 93 engages and rides upon a. shoe 95 secured to cam 94. As thearm drops off the abrupt edge of the shoe, spring 9% will rock bellcrank iii rapidly in a clockwise direction drawing toggle til, 88 acrossdead center.

During further rotation of the cam 94 the high portion will rock bellcrank 9i back to its initial position. It will be observed that theaction of the toggle is such as to reciprocate bail M, moving it rapidlytoward the left and then back again.

The mechanism for elevating carriage iii will now be described. Thecarriage is supported ohrods ill (Figs. 1 and 2) which are supported insuitable bearings in the frame of the machine. Link 98 connects theframe to cam follower member 99 whose rollers cooperate with a pair ofcomplementary cams tilt carried by shaft 66.

Carried by frame iii and adjacent to each pawl i9 is an overthrow pawliti having an arm M2 which, when the carriage it is in its lower orrestored position engages a fixed cross member M3 to hold the pawl miaway from the member 42. As the frame itmoves upwardly, pawl iui will befree to rock clockwise under the influence of its spring i lid and willmove into the path of tabs formed on member M. It will be recalled thatframe itl moves upwardly just as the carriage id is at the end of itsupward movement and the function of pawl MM is to prevent any overthrowof. type bar 35 due to the stopping of As the carriage it movesdownwardly to restored position, arm W2 engages member m3 and adepending arm itt of pawl it will also engage member tilt to retract thepawl for relatching by latch 5t The sequence of the various mechanicaloperations will now be reviewed with particular reference to the timingchart (Fig. 6) in which the more important operations arediagrammatically illustrated.

It will be noted that the upward rise of the operating cam Wt ofcarriage it commences before the cam "Sll has completely elevated thecarriage iii; so that for an interval the two carriages are movingtogether with the carriage l8 advanc ing at a slower rate. It will alsobe observed that the restoration by com 85 of the armature knock-01fball 34 occurs before the X and "R" index point positions are sensed bythe brushes UB or LIB. This, it will be observed, occurs after thecarriage I8 has commenced to rise but takes place before finger 8!(Fig. 1) has risen sufflciently to lie in the path of member 32. In theexample selected, that is, selection of the letter "P whose combinationperforation is represented by a '7 and an 11 hole, energlzation of themagnet 49 will occur as soon as the perforation is encountered butcoupling of the type bar to the carriage 44 is delayed for almost acycle point due to the mechanical action of the parts so that trippingunder control of the 7 hole results in commencement of the upwardmovement of the type bar just before the sixth position is analyzed. Theupward rise of the type bar, therefore, commences at the point indicated6fl'| of the line of cam 80 and proceeds seven steps with the upwardmovement of the carriage 44, after which the carriage dwells for aconsiderable period while the secondary carriage I8 completes itsmovement. The second perforation in the X position causes coupling ofthe type bar to the carriage H8 at the point indicated loll-X which isat a time when the carriage 44 is at rest. The frame is will thereforefurther advance the type bar two steps until it also dwells beforerestoration is efiected.

It will be noted that for alphabetic characters whose combinationsinclude either an X or an "R" perforation, the advance of the type baris in two distinct steps as the movement of the carriage 34 is completedand a numerical character presented to the printing line before the typebar is coupled to the secondary carriage which then advances it one ortwo additional steps. Where a zero perforation is part of acombinatlonal designation, the timing clmrt shows that a type bar iscoupled to the frame at the point Ind-ll. As pointed out above, thetripping of the pawl I9 occurs about a cycle point before this so thatthe pawl is in engagement with the notched member 42 and moving upwardlytherewith but at a slower rate so that immediately upon stopping ofcarriage 44, pawl I8 will pick up the type bar at point III-ll andcontinue its advance for three additional steps. The type bar is thusgiven a continuous movement from restored positionto the alphabeticprinting position without interruption.

Wiring diagram Referring now to Fig. 11 the entering circuits are shownas extending between lines M0 and i l I. The brushes UB receive currentfrom line HI through the usual card lever contacts UK'JL and circuitbreaker I II. The lower brushes LB receive current through lower cardlever contacts LCL and circuit breaker H3 while the special brush 28receives current through upper card lever contact UCLZ and a cam contactIll timed to make at 9. Record cards bearing name and address willcontain a perforation in the 9 index point position of the columntraversed by brush it so that the presence of such perforation willcomplete a circuit through clutch magnet 23 and further feeding will beinterrupted until the address card has passed both upper and lowerbrushes in succession.

It will be recalled that this declutchlng of the card feed will occurwhen contacts 34 are closed and contacts 33 open and the contacts willremain in this position throughout the analysis of the aosaaor card bythe upper brushes and the timing is such that as the card passes thelower brushes, contacts 33 will be closed and contacts 34 open.Therefore, as the address card passes the upper brushes, circuits willbe completed from line ill, contacts UCL, II2, brushes UB in the fieldof the card in which the name is perforated, connections H5, contacts34, print magnets id, to line H9. The first energization of magnets 59will efiect the primary selection of a digit and the secondary selectionwill effect the final positioning of the type bar to present the propercharacter. As the address card passes the lower brushes, the circuit formagnets 49 is traceable from line lll, contacts LCL, I I3, brushes LB inthe field in which the address" is perforated, through connections iI'o,contacts 33, magnets 49, to line H0. The address will thus be printed incolumnar alinement with the name.

The detail cards accompanying the address card may contain informationrelating, for example, to price in the field corresponding to that inwhich the name is entered on the address card and information relatingto, let us say, description, in the field corresponding to that in whichthe address is entered on the address card. In

4 order to read these fields of the detail cards and to prevent conflictin the circuits, a multi-contact relay H1 is provided which controlsnormally closed contacts H111 and a pair of contacts lllb.

The contacts Illa are wired to print magnets '29 in another section ofthe machine for printing in columns of the record other than those inwhich the name and address appear, for example, along the right handedge of the record shown in Fig. 12. Thus, as a detail card passesthrough the machine, it will traverse the upper brushes without thecompletion of any circuits since contacts 34 are open at such time. Asthe card passes the lower brushes, the circuits through the brushes LBin the price field will complete circuits through contacts la and theright hand group of magnets 49, while brushes LB, which traverse thedescription field, complete circuits through contacts 33 and left handgroup of magnets 49 in the same manner as explained in connection withthe circuits for printing the address.

When an address card arrives at the brushes, the special perforation inthe "9 index point position is sensed by the upper brush UB whichtraverses the column with the special perforation and completes acircuit from line III, contacts "UCL, II2, brush UB, cam contacts H8,timed to close momentarily at "9, relay magnet I I9, to line H3. RelayIIll closes its points II 902 which provide a holding circuit whichextends from line I I I to cam contacts I20, contacts I I So, relaymagnet H9, to line H0. Later in the cycle, as the address card is aboutto pass the lower brushes, cam contacts I 2| close momentarily,completing a circuit from line I l I, contacts I2 I, contacts I I9b, nowclosed, multi-contact relay Ill, to line IIO. Magnet II'I opens thecontacts ma so that the lower brushes traversing the main field of theaddress card do not complete circuits to the right hand group ofprinting magnets 49.

Closure of contacts lllb provides a holding circuit for relay III whichis traceable from line lII, cam contacts I22, contacts lI'lb, magnet H1,to line IN. This circuit is held while the address cam traverses thelower brushes. Reference to the timing chart (Fig. 6) will disclose thetiming of the several cam contacts mentioned. In Fig. 12 is shown aspecimen record in which the first two lines are printed under controlof the address card during the two cycles of the machine during whichthe address card passes the upper and lower brushes in succession. Theother three lines are printed under control of detail cards, there beingone line for each detail card and each line of data is printed undercontrol of the lower brushes only. In machines of this type themechanism for spacing the record is usually operative to effect a linespace for each cycle of operation so that the record will appear as inFig. 12 with a space between the address and the first detail line, thisspacing being brought about due to the cycle of operations during whichfeeding of new cards is suppressed so that during the cycle followingthe passage of the address card by the lower brushes there will be noprinting effected but record spacing will nevertheless take place.

The type bar 35 (Fig. 3) is, according to the preceding detaildescription, normally in restored or lowered position where it remainsunless and until its associated magnet 59 is energized at which time thetype bar is coupled to the invariably movable carriage M and therebypositively raised to printing position.

Just before it reaches this position, the over throw pawl fldi engagesthe type bar to prevent the possibility of overthrowing and carriage itas it moves upwardly may have the type bar 35 coupled thereto, in whichevent further positive upward movement is imparted to the bar to bringit to a final printing position. It will thus be apparent that the typebar 35 is at all times during its operating movement under the positiveand direct control of the frames of the carriages 44 or it and that anyretardation or overthrowing is efiectively prevented.

While there has been shown and described and pointed out the fundamentalnovel features of the invention as applied to a single modification, itwill be understood that various omissions and substitutions and changesin the form and details of the device illustrated and in its operationmay be made by those skilled in the art without departing from thespirit of the invention. It is the intention therefore to be.
